The flaw stems from trusting client-supplied GitLab provider configuration in the POST /api/auth/login/GITLAB_SELF_HOST endpoint. Attackers can set instanceUrl to a server they control that returns an active user with a chosen email. Bytebase then issues session tokens for that principal, letting attackers impersonate existing users including the Owner or create new members.","state":0,"publishedAt":"2026-10-22T19:13:18.259+00:00","modifiedAt":"2026-10-22T19:13:18.259+00:00","affected":[{"ecosystem":"Vendor product","name":"bytebase","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"bytebase\",\n                    \"product\": \"bytebase\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:golang/github.com/bytebase/bytebase\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.12.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.0.1\"\n                        },\n                        {\n                            \"version\": \"1.0.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/bytebase/bytebase\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/bytebase/bytebase/security/advisories/GHSA-5r3p-6rj5-7937","https://github.com/bytebase/bytebase/commit/d69e682243b25b51dd52912a26e2f259b5f3db2d","https://github.com/bytebase/bytebase/pull/834","https://github.com/bytebase/bytebase/blob/1.0.0/server/auth.go#L79-L93","https://github.com/bytebase/bytebase/releases/tag/1.0.1","https://github.com/bytebase/bytebase","https://www.vulncheck.com/advisories/bytebase-0.12.0-before-1.0.1-authentication-bypass-via-gitlab-self-hosted-login"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-51026","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-51026","identifiers":["CVE-2022-51026"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
